April 23, 2018, update: Regina Williams pleaded guilty to neglect of a dependent resulting in bodily injury and was sentenced Feb. 6 to four years in prison with one year suspended, online court records say.

Earlier story: A mother accused of abducting her 5-month-old son over the weekend has returned the child to Indianapolis.

The Indianapolis Metropolitan Police Department tweeted Tuesday morning a photo of 37-year-old Regina Williams and her son, Parker Williams, at the City-County Building.

Detectives announced Saturday that the pair was missing.

Police said Parker Williams is a ward of the state who recently suffered a skull fracture.

Regina Williams currently faces a charge of neglect of a dependent resulting in bodily injury stemming from a Jan. 17 incident, according to court documents.

She took the infant to the hospital, where doctors diagnosed his skull fracture, and told doctors that she had slipped and fallen when stepping off a staircase and onto a wet floor and dropped him.

Doctors contacted police, however, because the boy's injuries did not appear to be consistent with what Regina Williams had told them happened.

Family members interviewed by police told them Regina Williams had been drunk at her mother's house and was holding the baby with one arm around his legs, but dropped him when she stood up, causing him to hit his head on the tile floor.

In this incident, investigators believed she may have taken the child across state lines to Louisville, Ky.

Police did not disclose where Parker was when he was abducted. It is unclear what new criminal charges Regina Williams will face for her role in the incident.
